The invention provides an AGV chassis structure capable of adapting to ground deformation. The AGV chassis structure comprises a bearing vehicle frame, a first movable vehicle frame, a second movable vehicle frame, a drive device and bearing wheels. The inner end of the first movable vehicle frame and the inner end of the second movable vehicle frame are hinged through a hinging shaft. The drive device comprises drive motors, drive shafts and drive wheels, wherein the drive shafts are coaxially connected with the hinging shaft, and the drive motors drive the drive wheels through the drive shafts. A first hinging hole is formed in the first movable vehicle frame, a second hinging hole is formed in the second movable vehicle frame, the bearing vehicle frame is hinged to the first hinging hole through a first connecting pin and hinged to the second hinging hole through a second connecting pin, and the second hinging hole is a kidney-shaped hole. When the first movable vehicle frame and the second movable vehicle frame relatively rotate around the hinging shaft, the first connecting pin moves relative to the first hinging hole, and the second connecting pin moves relative to the second hinging hole. When the AGV chassis structure encounters the uneven ground, the first movable vehicle frame and the second movable vehicle frame rotate relatively, it is guaranteed that the drive wheels are landed, and the uneven ground is adjusted.

The invention discloses a wheeled mobile robot suspension device. The device is characterized by comprising a chassis (1), the middle of the chassis (1) is provided with a first through hole through which a wheel (15) can penetrate. The portion, at the front end of the first through hole, of the chassis (1) is fixedly provided with a spring guide rod fixing base (2). The portion, at the rear end of the first through hole, of the chassis (1) is fixedly provided with a supporting base (6). According to the wheeled mobile robot suspension device, it can be ensured that a driving wheel is landed always, the ground adaptive capacity of the chassis of a robot is improved, the phenomenon that the driving wheel is suspended by a driven wheel, and therefore the driving wheel idles or slides to affect robot movement is avoided, meanwhile, vibration transferred to the robot chassis when the wheels of the robot move on the ground can be effectively relieved, and the device is simple in structure and convenient to control.

The invention belongs to the field of industrial automation and particularly relates to a four-wheel-driven robot self-propelling chassis with rocker shafts. The four-wheel-driven robot self-propelling chassis comprises a chassis body (1), a connection mechanism (15), a front shaft steering system, a rear shaft drive system and a hydraulic lifting system, wherein the connection mechanism (15) is arranged on the chassis body (1); the front shaft steering system is arranged on the front portion of the chassis body (1) and comprises a steering stepping motor-speed reducer set (4), a front shaft (3), a steering system bearing (5), a front shaft bevel gear (6) and steering wheel systems (2); the rear shaft drive system is arranged on the rear portion of the chassis body (1) and comprises a drive motor-speed reducer set (11), a rear shaft (12), a drive system bearing (13), a rear shaft chain wheel (9) and drive wheel systems (8); and the hydraulic lifting system comprises a hydraulic cylinder (14), a hydraulic oil source system, a synchronous valve and a hydraulic pipeline, and the hydraulic cylinder (14), the hydraulic oil source system and the synchronous valve communicate through the hydraulic pipeline.

The invention discloses a precise positioning and fixing device for assisting the landing of the drone, which solves the problem of poor positioning accuracy of the landing of the drone in the prior art. The work provides convenience, and the scheme is as follows: a precise positioning slot for assisting the landing of the drone, including a limit slot for limiting the arm of the drone, the limit slot includes a flat brace set at the bottom, a flat brace The side is connected with the landing surface, the landing surface is a flat or curved surface, and the landing surface and the flat support are set at an angle. After the support leg of the UAV arm contacts the landing surface, it falls onto the flat support along the landing surface to achieve precise positioning.

The invention provides a steel bar trolley suitable for construction of a turning section. The steel bar trolley comprise a steel bar trolley truss, a plurality of layers of side face platforms located on the two sides of the steel bar trolley truss correspondingly, trolley crawling ladders, traveling systems and a rail. A plurality of sets of connecting holes are formed in two corresponding bottom longitudinal beams of the steel bar trolley truss. Each traveling system comprises a traveling longitudinal beam, inner traveling steel wheels and outer traveling steel wheels, wherein the inner traveling steel wheels and the outer traveling steel wheels are installed on the traveling longitudinal beam and driven by a motor through a sprocket-chain transmission mechanism to travel on the rail, and the diameter of the inner traveling steel wheels is smaller than that of the outer traveling steel wheels. Traveling wheel hinging seats are hinged to the traveling longitudinal beams through rotary shafts. Connecting seats are installed at the tops of the traveling wheel hinging seats. A plurality of connecting holes are formed in the connecting seats. The connecting seats are connected with the bottom longitudinal beams in the steel bar trolley truss by means of connectors through the connecting holes in the connecting seats and connecting holes in the bottom longitudinal beams. According to the steel bar trolley, the universality is high, the traveling speed of the trolley is high, the requirement that the trolley operates to a specific position smoothly through turning can be met, and safety is achieved.

The invention discloses a suspension device for a wheeled mobile robot. Two first through holes used for two wheels (11) to penetrate through are formed in a chassis (1), two supporting bases (2) are fixedly arranged in the middle, between the two first through holes, of the chassis (1), are arranged oppositely and are each horizontally provided with two second through holes used for rotating shafts (6) to penetrate through, each rotating shaft (6) is fixedly connected with one end of the corresponding wheel support (7), the other ends of the two wheel supports (7) are connected with the two wheels (11) respectively, a gap is formed between the two wheel supports (7), and plate springs (4) are arranged at the opposite ends of the two wheel supports (7). The suspension device for the wheeled mobile robot relieves robot jolting caused by wheel vibration, improves driving stability of the robot, can adjust the distance from the driving wheels to the ground, and guarantees that the wheels touch the ground all the time.
